1. Plot procrastination: Some viewers criticized that the plot development was too procrastinating and lacked a compact rhythm, which led to a cumbersome viewing process.

2. Unreasonable role setting: Some viewers think that the role setting in the play is not realistic enough and lacks depth. Some characters only exist in the play to increase the drama conflict and lack reasonable plot bedding.

3. Acting and script problems: Zhao Lusi's performance has been questioned, and the audience thinks that her performance is too single and mediocre, lacking the true transmission of emotions. In addition, some people think that the creation and dialogue of the script are too mediocre and the expression is not smooth and natural enough.

Although "Back Waves Push Forward Waves" won a bad review, some viewers still affirmed the inspirational theme of youth and Zhao Lusi's acting skills. Evaluation is always subjective, and everyone will have different views on the same play. I suggest you look at it yourself and form an independent evaluation, because your preferences may be different from others.
